try using 'Handbrake' (google it) choose you source and select the preset 'classic'. you can fiddle with advanced settings for higher quality but i know the preset works and is reletively fast almost to the point of a twenty minute video taking twenty minutes. also i suggest you use Mp4/avi(ffmpeg) rather then Xvid as Xvid is already compressed which takes time. Emodio with compress the video on transfer and convertion to .svi
